First paper from my postdoc is out in WRR with open access!

We explored how contrasting watershed features influence NO3 and DOC transport and transformation in an agricultural watershed

So excited to have this paper from my dissertation out! We explored shifts in the interactive effects of climate, deposition, and watershed properties in driving lake DOC over the past 40 years. Open access ⬇️ link.springer.com/article/10.1...

Climate displaces deposition as dominant driver of dissolved organic carbon concentrations in historically acidified lakes - Biogeochemistry

Climate and atmospheric deposition interact with watershed properties to drive dissolved organic carbon (DOC) concentrations in lakes. Because drivers of DOC concentration are inter-related and intera...

My first postdoc paper is live and open access!

Here was asked a simple question: what happens to methane in canals draining tropical peatlands? Turns out, lots of it is consumed by methanotrophs!

Fate of methane in canals draining tropical peatlands - Nature Communications

Canals draining vast areas of peatland in Southeast Asia may be hotspots for methane emissions. Perryman et al. surveyed dozens of canals in Indonesia and found that methane-eating microbes reduce emi...

Happy to share this paper led by @carlalopezpr.bsky.social assessing drivers of #CO2 & #CH4 in headwater #wetlands! Recently published #OA in #Ecosystems: link.springer.com/article/10.1...

#wetland #biogeochemistry #carbon #water #DelmarvaDisco
💧🧪🌎👩‍🔬

Fig 1 from the paper is a multi-panel plot showing the location of our study sites on the Delmarva peninsula of Maryland and within a landscape with many headwater headwater wetland complexes. The graph in the bottom right corner shows the range of wetland areas (<500, >5000 m2) and mean water levels (0.1-0.8m) at our core study sites.

Three panel plot showing (a) lower CO2 concentrations in wetland surface water compared to shallow groundwater adjacent to each study wetland, (b) higher CH4 concentrations in wetland surface water compared to shallow groundwater, and (c) positive relationships between CO2 and CH4 for surface water (R2 = 0.2) and shallow groundwater (R2 = 0.4).

Six panel plot showing (a) no relationship between wetland area and CO2, (b) a positive relationship between wetland perimeter:area and CO2, (c) a slightly positive relationship between height above drainage network [HAND] and CO2, (d) a negative relationship between wetland area and CH4, (e) a positive relationship between wetland perimeter:area and CH4, and (f) a positive relationship between height above drainage network [HAND] and CH4

Had a great time at #AGU24 presenting my first talk on drivers of aquatic CO2 emissions in Greenland and meeting friends new and old!
